Candy, fruit juice and other snack foods are the most common sources of the dye, which is still found in more than 2,800 items on American shelves.
The FDA announced it will ban the use of Red Dye No. 3 in food products and ingested drugs, decades after it was banned in cosmetics and externally applied drugs for its link to thyroid cancer in animals.
Red No. 3 is significantly more regulated in other parts of the world, including in the European Union, where it is only authorized for use in cocktail and candied cherries, and in Korea, where the use of most synthetic colors is prohibited in certain foods eaten mostly by children and teenagers.
Manufacturers who use Red No. 3 in food or medications will have 2 years to reformulate their products, and the ban applies to all internationally made products imported into the U.S.
Red No. 3 or erythrosine, a color additive made from petroleum, could previously be used in foods in small amounts as approved by the FDA on a per-case basis.
